A carbon nucleus has six protons and six neutrons. How many electrons would it take to equal the mass of a carbon nucleus?
ok. i think theres some type of formula or some trick to figure this one out but i don't know what it is. If you guys know how to figure this out can u tell me then i will try to get the answer and post it so u can check it:) Thanks!
look up the three masses, solve for n.
An close estimate of n will be 12*1760, since one electron is 1/1760 th of the mass of a nucleon.
thanks. im stuck on finding the masscarbon though. i searched on google and nothing comes up with the mass of a carbon.
i got 7.9X10^28 for some weird reason. is the mass of carbon. .012011?
wut am i doing wrong?
